Constantine Metal Resources released a new mineral estimate at its AG Zone, a new deposit at the Palmer Project 30 miles north of Haines, which has increased the total resource tonnage by 43 percent, according to the mineral exploration company.

The AG Zone is the second deposit to be defined by Constantine, which completed a second season of drilling in the area. “Located just three kilometers from the main Palmer Deposit, AG Zone has potential to have a positive impact on the economics of the project,” a press release says. “It also clearly confirms the multi-deposit district potential of the 81,000- acre property. The opportunity to discover additional deposits and expand the two known resource areas is considered excellent.”

The main Palmer deposit consists primarily of copper and zinc. The AG Zone contains higher grades of silver, gold, lead and barite and similar grade zinc.

The company has estimated the total mineral resource at 4.26 million metric tons of 9 percent zinc equivalent in the AG Zone—a number that combines grades of zinc, copper, silver, lead and gold.

Constantine vice president of community affairs Liz Cornejo said they are reporting zinc content because the metal is currently a profitable commodity.

“The rapid evolution of the AG Zone from discovery to maiden resource has increased the value of this deposit in a very short time,” Constantine president Garfield MacVeigh said in the press release.

The total consolidated mineral resource now stands at 4.68 million metric tons of 10 percent zinc equivalent at higher levels of confidence compared to the 9.5 million tonnes of inferred zinc equivalent resource estimates.

The deposit will be incorporated into the preliminary economic assessment that is currently underway, said Cornejo, set for release in early 2019.
